Abstract
The invention relates to high attitude work, especially a high-rise pillar segment work method. The high-rise pillar segment work method comprises a plurality of double pipe string pillars having lifting lugs, and includes the following steps: the first step, arranging steel bar straight ladder along the length direction from down to up on the surfaces of the pillars; the second step, arranging a safe platform on the top ends of the double pipes of the pillars provided with the straight ladder; the third step, vertically arranging the pillars provided with the safe platform by lifting equipment through the lifting lugs, and the worker can get on the safe platform through the straight ladder; the fourth step, lifting the other pillars which are not provided with the safe platform, and the worker can butt joint the two segments of pillars on the safe platform; and the fifth step, dismounting the safe platform, and repeating the second to the fourth steps to complete the butt joint work for all the pillars.
Description
Technical field
The present invention relates to senior engineer's operation, relate in particular to a kind of high layer post subsection operational method.
Background technology
To the lifting of superelevation overlength, ultra wide, overweight member, the construction safety technical difficulty that is faced is: 1. the overlength member can't transport in heavy (high level) mill construction; 2. town road restriction transportation; 3. site condition can't satisfy the lifting ability restriction that the requirement of large-scale loop wheel machine erect-position causes; 4. the member appearance can not be provided with too much complementary temporory structure; 5. work high above the ground is used frequent and is removed difficulty.When being installed in the past, this type structure is difficult to satisfy safe and reliable technical requirements.Like installation for the cold rolling factory building four tubing string segmentations of certain unit butt joint (long 54.5 meters, wide 4 meters, weigh 113 tons); Adopt conventional technical safety measures; Consider that large-scale loop wheel machine can't use, town road transports situation such as restriction because of the site condition restriction causes; Can only segmentation install; Every section pillar needs butt welding to be connected to design height, and how weld job guarantees that operating personnel's personal safety does not have good solution for a long time in the high-altitude, and the high-level placement of welding equipment simultaneously also is a problem.
Summary of the invention
The present invention is intended to address the above problem, and a kind of high layer post subsection butt joint operational method is provided.Job platform of the present invention is the strong scheme of a kind of feasibility really for technical safety measures, not only simple science, and also practical, convenient.High-rise member must the segmentation butt joint and safety measure formulate under the difficult situation realization constructor from ground to the high-altitude the safe vestibule of docking operation point, flexible, workable, safe and efficient, economize on resources to reach.
The present invention is achieved in that a kind of high layer post subsection docking calculation; It comprises some to having the dual string pillar of hanger, and it comprises the following steps:
Step 1, on the surface of some pillars, the elongated along its length from bottom to up reinforcing bar catladder that is provided with;
Described high layer post subsection docking calculation; In the said step 1; Said catladder is provided with the cage that protects of corresponding semicircle cover shape, and the said two ends of protecting cage are fixedly connected the dual-side of catladder, and and catladder common form one from ground to escape way said security platform.
Described high layer post subsection docking calculation; Said security platform comprises a flat board, is provided with railing around the flat board, is provided with through hole in the flat board to hold high-rise pillar; Dull and stereotyped bottom is provided with clamp near the pillar position; In the said step 2, the buckle of some and said clamp respective numbers is set on the pillar side face, platform is fixedly connected with pillar thereby said clamp inserts buckle.
Described high-altitude pillar segmentation docking calculation, said security platform bottom also is provided with triangular support bracket, and the plumbing bar of said triangular support bracket is fixed on the said pillar.
Described high-altitude pillar segmentation docking calculation, in the said step 2, said security platform bottom also is connected with safety net.
Described high-altitude pillar segmentation docking calculation in the said step 3, draws in the pillar aperture and to establish the life rope, directly is bundled on the dual string pillar; The operating personnel all need hang up properly safety belt when decoupling device, butt joint connection, welding procedure, buckle of safety belt point is being arranged on the life rope at man-hole opening place.
The method that the present invention adopts is to adopt special-purpose temporary platform, through from being arranged on the guarding cage vertical ladder on the pillar, begins from ground until temporary platform is provided with a little, even arrives pillar top and crane girder etc. frequent point is installed, and can form a safe corridor.After being used to complete, temporary platform can conveniently be removed again, is convenient to second use, and convenient and swift also the meaning during dismounting reduced potential safety hazard.Installation and removal are all very convenient, and with the elongated reinforcing bar catladder of pillar with protect the cage supplementary measures, form a safe corridor fast and easily.In the actual security control of engineering construction, easy for installation, flexible operation has reduced construction cost, plays remarkable result, is applicable to the frequent lifting of factory building work high above the ground of the same type.
Description of drawings
Below, in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is a sketch map of the present invention;
Fig. 2 is an A-A sectional view among Fig. 1.
The specific embodiment
A kind of high layer post subsection docking calculation; It comprises some to having the dual string pillar 1 of hanger, and it comprises the following steps:
Step 1 sees also Fig. 1, at the elongated along its length from bottom to up reinforcing bar catladder 3 that is provided with of some pillars 1; What said catladder 3 was provided with corresponding semicircle cover shape protects cage 4, and the said two ends of protecting cage 4 are fixedly connected the dual-side of catladder 3, and and catladder 3 is common forms an escape way between 1 top from ground to the pillar; This passage is the current up and down security protection passages of convenient working personnel.The decoupling device of epimere pillar will be accomplished through this catladder.
